What is the best Ph factor for a hotel swimming pool?

Answer 1

pH for a swimming pool should be between 7.3 - 7.6 this will ensure bather comfort and maximum disinfectant efficiency.

Increasing the pH of the water without affecting the alkalinity is very easy, but there is a trick. With the pump motor on and water circulating, add the sodium bicarb. in the deep end of the pool and work your way around the perimeter. This will raise the pH with minimal effect on the alkalinity.

Keep your pH around 7.6-7.8, not 7.2-7.4. Most "pool experts" tell you 7.2-7.4 but they are using an index that your local water company uses which obviously should not be used for pool. There's a big difference between a water treatment system and your pool. You can't treat them the same.

Having a properly balanced pool is not difficult, but it does take work.

I'm the pool operator at our local YMCA and keeping an 80,000 gallon pool balanced is pretty easy, once you have all the elements in place and know what you're doing.

Chlorine 3.5-4.5, alkalinity 80-100, pH 7.6-7.8, not 7.2, hardness 150-250, not up to 400.

You have to stay on top of it because the chlorine can go down in a matter of hours if no one properly checks it.
